Abstract

The article sets forth a three-dimensional linearized theory of a supercavitating pump or hydroturbine with finite dimensions of the blades and cavities, in a tube of round cross section. A fundamental solution is constructed (the potential of a source in a tube), and numerical methods are indicated for solution of the direct and inverse problems, required for the detailed design and calculation of axial hydromachines, under conditions of developed cavitation. Some results of the calculations are given.
